Option Greeks measure how an option's price responds to changes in the stock price (delta and gamma), time (theta), implied volatility (vega), and interest rates (rho).

Gamma, theta, and vega are largest for strikes near the Delta Air Lines stock price and shrink for strikes far above or below it. Theta grows as expiration gets closer, while vega is larger for expirations further out. Call delta runs from 0 to 1 and put delta from -1 to 0, near 0.50 and -0.50 at the money, and roughly estimates the chance that an option finishes in the money.

Delta Air Lines IV rank is 36, so implied volatility is in the lower part of its one-year range. Higher implied volatility raises option premiums and daily time decay (theta), and spreads delta and gamma across a wider range of strikes. Over the past year, 30-day implied volatility ranged from 31.3% to 63.5%. See the DAL implied volatility history for a longer view.

Across all open Delta Air Lines options on Nov 4, 2026, net gamma exposure was $86.93M and net delta exposure was $1.91B per 1% move in the stock. The DAL gamma exposure chart shows where that gamma sits by strike.

Atlanta-based Delta Air Lines is one of the world's largest airlines, with a network of over 300 destinations in more than 50 countries.
